Be it known that I, Fuhrer; H. STEIFEL, a, citizen of the United States and a resident of'Jersey City Heights, in the county of Hudson and State of New Jersey, have invented certain new and useful Improve ments in Linotype-Slugs, of which the to lowing is a specification. 1

The main object of my invention is to obviate all'danger of s'mu'dging or soiling 1 the paper duringprinting by reason of the,

contact of the paper with the upper quad line edge of the slug below the faces of-tlie type ;-and by type slug, I herein. mean todesignate a plate of metal with typehighletters or characters cast thereon in. the usual way. by neans of type matrices as in the lllergenthaler and similar Linotype machines. Heretofore the upper quad line edges of these type slugs below the type faces, hav'ecxtended but little below typehigh, which is not objectionable where the solid line is full of type-faces practically sembled and held closely against the face from one end to the other. But where either end of the line is lacking to any con siderable extent in "ftype-high printing surfaces there is danger of the inking of such depressed quad linesurface or surfaces of the upper edge of the type slug; and hence of the staining-or smudging of the paper printed upon. Under present conditions this is a serious obstacle. and objection in book work, newspaper work, the printing of testimony, as, where many lines are only partially set up and occupied by type pri'nting faces,resulting in inferior prints, frequently to such an extent as to necessitate discardlnent.

As is well known, in casting the linotype bars or slugs the type matrices are asof" the mold. closing the saine, and hence the depth of the matrix grooves determines the depth of the front edge of the cast slug below type-high 2'. e., below the faces of the printing type. This diii'erence between type high and the height of the restof the slug has heretofore been only suiiicient to afford suitable relief base for the type so faces, with the resultantdefects in printing hereinbefore set forth.

My invention consists in obviating this difficulty by increasing the diii'erence in 'height between the type-high printing facesand the rest of slug especially the quad line or lines sufiiciently to remove said Specification of Letters Iacent. Application plea. June le s. Serial No. 36,026.

In the accompanying drawings, Figaro 1,

IS a diagrammatic perspective of a mold carrying-wheel of well known construction and use in connection with linotype' apparatus; Fig. 2, perspective view of one of the molds; Fig. 3, a side elevation ofa typeniatrix used in such apparatus; Figs. at, and 5, respectively front edge and side views of my improved linotype slug.

In the drawings VJ represents an ordinary mold wheel such as used in linotype apparatus, and M, tached therefrom and shown on a larger scale. y

T, is one of a series of ordinary so called type matrices, formed with the upper and lower type case grooves a, t, manner except that they are made one sixteenth of an inch (more or less) deeper than hereto ore-Tit being understood that the intaglio outlines of the types arezforined in the inner or bottom faces of the grooves in the manner wellknown in the art. To compensate for this increase of the depth of the type grooves 25, t, I make the cast groove m, in the mold M, of correspondingly less depth, so that the resultant cast or type slug 8, will be standard type-high at the prino an ordinary mold dein the ordinary ing surfaces 8, a, but considerably less than portions 8', s, as shown more particuof its front edge,

5, in which the depressions s larly in Fig.

represent the depth or base line of the letters Y or characters as distinguished from the quad line portions 3', a, of the slug S,

By this simple change in form and nianufacture of linotype slugs I attain results of vast importance in this branch of the art of printing, incrcial sense, since all fsmudging or soiling of the paper printed upon is entirely eliminated. because the quad line portions 3, s, of the front edge of the slug S, below the printing faces 3, s, are so positioned that contact with inking roller or print paper is rendered impossible under ordinary, conditions of use.

There. is-another incidental advantage at taincd by my invention, and that is the fact that stereotypes. made from nay new form of considered in a. practical, com-' danger of the drawing.

linotype do not have to be routed out to remove superfluous metal that would otherwise prevent the production 'of good, clear printing,-thus saving the initial cost of expenslve routing mechanism, as well as the cost of skilled labor,-the stereotypes being. ready-.foruse as cast.

The spaces between the letters and words of type high printing matter are relatively slight, so much so as slon of the front edge 3, of the quad line must be below the base line 8, of the type characters and below the base line of the relief base or pedestal in order to be efiec-' tive, and by type base line we -mean the depth of depression 8 between adjacent letters of a word as shown in Fig. 5, of the -I am aware that linotype slugs havebeen formed with rule-slots for, the accommotopreventthe inking 'ofthe intervening parts ofthe-slug. It is Witnesses:

line, as usual, with the baseline of the characters to be. printed from, whereas the whole gist of my inventionconsists in formingthe slug with the quad lines, below the base line 8 of the type characters.

- .What I claim as my'invention and desire to secure by Letters Patent is,

A linotype slug of the character designated formed with type high surface printing characters, said printing characters being supported on a pedestal, with the quad line front edge below the base line of said printing characters and below the base line of the pedestal so as to prevent the contact of said quad-line edge withink roller or surface to be printed upon, as set forth.
